Xbox One vs PS4 article: http://www.engadget.com/2013/11/18/xbox-one-ps4-differences/?utm_medium=feed&utm_source=feedly

This sums up my opinion. It seems like the only two reasons to chose PS4 is price and hardware speed. Almost all games are developed on the lowest common denominator console first, historically having been developed on Xbox 360 before porting over to PS3, there should be no noticeable difference between the games. In many cases, it may look better on Xbox One because it was developed on it first before porting over to PS4. This is exactly what happened with the PS3 which had faster hardware.

My only case for buying a PS4, which I plan to later, is for 1st party exclusives. These games tend to be delayed so it may take some time before anything worthwhile comes out.
